Time = 6hours
Distance = 38.4 Km
Speed = distance /time
= 38.4/6
= 6.4 km/h
C 3*3 = 9 6*6=36 and 36 plus 9 is 45 and 9*9 = 81 so it’s not equal and not right.
The legs are 5 inches long.
Use the Pythagorean theorem:

➷ It would help if you drew it out as a triangle
You will notice that you need to use tan
tan70 = 39/x
x = 39/tan70
x = 14.194
The correct option would be 14.2 ft
You will need to use tan
tan51 = 6/x
x = 6/tan51
x = 4.8587
The correct option would be 4.9m
